travis ci hooks

[kreig303]

we have a .travis.yml but the hooks aren't set up to trigger it on PRs.

@kreig303 we can get rid of this, I believe it was a product of the scaffolding process when running create-probot-app.

@Hollywood i would rather we didn’t. we can actually setup a project on travis-ci.org to do the ci on repo actions like push or prs. i’ve used it on other projects. it would have some actual utility.

as you are the repo owner and i can’t add hooks with my rights it would be up to you to set it up. alternatively i could set it up on my fork so you get an idea of how it works.

of course until #18 is addressed every build will fail 😌
